13.3 Analytical procedures – ISSAI 4100

• What are analytical procedures?

ISSAI 4100 paragraph 109/4200 paragraph 116: Analytical procedures involve comparing data, or investigating

fluctuations or relationships that appear inconsistent. In compliance auditing, such procedures may, for example, involve comparing an increase in pension benefits payments from one year to the next with demographic information such as the number of citizens having reached retirement age within the last year. If the criteria relate to the terms of an agreement which state, for example, that project funding is provided based on performance levels such as the number of job placements made, then any changes in project funding might be

compared to changes in employment statistics.

A municipalities budget shows a decrease in local tax income for four consecutive years. The auditor compares the trend with:

b) Tax level

Is this a correct analysis?

13.8 Analytical procedures – True or False?

• A ministry has announced an end to a subsidy scheme as of 31 March on 1 April, allowing all requests arriving on or before 1 April to be considered. The amount spent was within budget.

• The auditor makes an overtime analysis of the amount accounted and notices a significant decrease in April from August and no payment afterwards

Is this a correct analysis?

13.9 Analytical procedures –True or false?

After the compliance of a ministry has been examined the HSC reviewer asks you what the explanation is for the increase in the spending in budget item X. You answer that budget item X was reviewed looking at the top 10 items included and no irregularities were found.

Should the reviewer accept this explanation?

13.12 How many? A possible decision tree

15

No

No

Either expand targeted testing or perform substantive analytical procedures, non-statistical sampling or accept-reject testing on untested items. Reconsider the option to achieve a higher level of controls testing as well.

Can we efficiently test items?

Perform TARGETED TESTING

No further testing required

(document rationale/conclusion)

Yes

Possible & appropriate to project misstatements?

Yes No

Perform ACCEPT-REJECT

TESTING

Perform NON-STATISTICAL

SAMPLING

Yes

Considering the results of tests of controls, substantive analytics and targeted testing, do we need more assurance with regard to the untested items?

Are the aggregated untested items above materiality?

Can we select items within an account or population based on a higher value, higher risk, or other characteristic to

address our test objective?

No

No Yes

Yes
